Question: A machine produces metal rods used in an automobile suspension system. A random sample of 15 rods is selected, and the diameter is measured. The resulting data are shown below:
| 8.24 mm | 8.23 mm | 8.25 mm | 8.26 mm | 8.20 mm |
| 8.21 | 8.20 | 8.19 | 8.23 | 8.28 |
| 8.23 | 8.26 | 8.25 | 8.24 | 8.24 |
Is there sufficient evidence to indicate that the mean rod diameter exceeds 8.20 mm using \(\alpha =\) 0.05?
